There is no failure. There is clearly nothing wrong with the boundary conditions because your boundary conditions are satisfied in both cases. You're not solving the same problem. charge, electrons, holes, idonors, and iacceptors are not arbitrary values. They are densities. Printing holes.cell

Hello Daniel, Thanks for the insight, having a large project which is still light weight and transparent is a challenge so I understand that approach. My interest in the CV approach came about because my 1D FVM code fails when trying to solve a particular electrostatics problem. I coded up the

Dear list, When reading through the FiPy docs, http://www.ctcms.nist.gov/fipy/documentation/numerical/discret.html I noticed that discussion of vertex centred (CV) and cell centred (CC) meshes. I'm just curious, why did you decided to implement FiPy with CC approach. Did you find some advantag
